Local government stakeholders' perceptions of potential policy actions to influence both climate change and healthy eating in Victoria: A qualitative study.

ISSUE ADDRESSED: Climate change is a defining public health issue of the 21st century. Food systems are drivers of diet-related disease burden, and account for 30% of global greenhouse gas emissions. Local governments play a crucial role in improving both the healthiness and environmental sustainability of food systems, but the potential for their actions to simultaneously address these two issues is unclear. This study aimed to explore the perceptions of Australian local government stakeholders regarding policy actions simultaneously addressing healthy eating and climate change, and the influences on policy adoption. METHODS: We conducted 11 in-depth semi-structured interviews with stakeholders from four local governments in Victoria, Australia. Data were analysed using reflexive thematic analysis. We applied Multiple Streams Theory (MST) 'problem', 'politics and 'policy' domains to explain policy adoption influences at the local government level. RESULTS: Key influences on local government action aligned with MST elements of 'problem' (e.g., local government's existing risk reports as drivers for climate change action), 'policy' (e.g., budgetary constraints) and 'politics' (e.g., local government executive agenda). We found limited evidence of coherent policy action in the areas of community gardens, food procurement and urban land use. CONCLUSION: Barriers to further action, such as resource constraints and competing priorities, could be overcome by better tailoring policy action areas to community needs, with the help of external partnerships and local government executive support. SO WHAT?: This study demonstrates that Victorian local stakeholders believe they are well-positioned to implement feasible and coherent interventions that address both healthy eating and climate.

A systems framework for implementing healthy food retail in grocery settings.

BACKGROUND: Food retailers can be reluctant to initiate healthy food retail activities in the face of a complex set of interrelated drivers that impact the retail environment. The Systems Thinking Approach for Retail Transformation (START) is a determinants framework created using qualitative systems modelling to guide healthy food retail interventions in community-based, health-promoting settings. We aimed to test the applicability of the START map to a suite of distinct healthy food marketing and promotion activities that formed an intervention in a grocery setting in regional Victoria, Australia. METHODS: A secondary analysis was undertaken of 16 previously completed semi-structured interviews with independent grocery retailers and stakeholders. Interviews were deductively coded against the existing START framework, whilst allowing for new grocery-setting specific factors to be identified. New factors and relationships were used to build causal loop diagrams and extend the original START systems map using Vensim. RESULTS: A version of the START map including aspects relevant to the grocery setting was developed ("START-G"). In both health-promoting and grocery settings, it was important for retailers to 'Get Started' with healthy food retail interventions that were supported by a proof-of-concept and 'Focus on the customer' response (with grocery-settings focused on monitoring sales data). New factors and relationships described perceived difficulties associated with disrupting a grocery-setting 'Supply-side status quo' that promotes less healthy food and beverage options. Yet, most grocery retailers discussed relationships that highlighted the potential for 'Healthy food as innovation' and 'Supporting cultural change through corporate social responsibility and leadership'. CONCLUSIONS: Several differences were found when implementing healthy food retail in grocery compared to health promotion settings. The START-G map offers preliminary guidance for identifying and addressing commercial interests in grocery settings that currently promote less healthy foods and beverages, including by starting to address business outcomes and supplier relationships.

Diet-Related Disease Prevention in a Rural Australian Setting: Understanding Barriers, Enablers, and the Role of Rural Health Services in Supporting Changes in Local Rural Food Environments.

Bold and comprehensive action is needed to prevent diet-related diseases in rural areas, which includes improving food environments to enable healthier dietary practices. Rural health services are integral to the health of rural populations, yet their role in community disease prevention is not swell understood. This study sought to understand health service, local government, and food outlet stakeholders' perspectives on (1) the drivers of unhealthy retail environments in a rural setting; (2) the role of rural health services in supporting changes in local food environments; and to (3) identify characteristics of potential interventions. Two Group Model Building workshops were held with health service and local government leaders (n = 9), and interviews were conducted with local food outlet participants (n = 13). Key themes included 'enablers to healthier food environments', 'barriers to healthier food environments', 'Rural health services are a leading broker of knowledge for healthy food environments', and 'characteristics of desirable healthy food environment interventions.'. Rural health services can play a key role in addressing the current barriers to healthy food environments in rural areas. Effective promotion of healthier diets in rural populations will require consideration of key stakeholder perspectives and the development of further evidence on the role that rural health services can play in improving the healthiness of food environments.

CO-Creation and Evaluation of Food Environments to Advance Community Health (COACH).

Introduction: Food environments are a key determinant of food intake and diet-related health. This paper describes the development of an iterative, adaptive, context-specific framework for health-enabling food environments embedded in cocreation theory. Methods: A 3-stage multimethod framework for the coproduction and prototyping of public health interventions was followed in an iterative manner during the development of the framework. These 3 stages were (1) evidence review, including systematic review, consultation with experts, and observation of current work; (2) codesign of the framework prototype with multiple stakeholders; and (3) coproduction through refinement of the prototype through stakeholder workshops and expert reviews with incorporation of researcher notes and workshop evaluation. We use the term prototype during the development phase and the term framework to report on the final product. Results: COACH (CO-creation and evaluation of food environments to Advance Community Health) is a process framework that describes what best practice application of cocreation in health-enabling food retail environments should involve. COACH consists of 10 interdependent factors within a 4-phase continuous quality improvement cycle. The 4 phases of the cycle are engagement and governance establishment, communication and policy alignment, codesign and implementation, and monitoring and evaluation. Conclusions: Utilizing cocreation theory represents an innovative step in research and practice to improve the healthiness of food retail environments. COACH provides a specific, unique, and comprehensive guide to the utilization of cocreation to improve the healthiness of food environments in practice.

Combining systems thinking approaches and implementation science constructs within community-based prevention: a systematic review.

BACKGROUND: Systems science offers methods for designing population health interventions while implementation science provides specific guidance for successful implementation. Integrating systems and implementation science may strengthen implementation and enhance and sustain systemic change to achieve system-level outcomes. Little is known about the extent to which these two approaches have been integrated to date. This review aimed to identify and synthesise the peer-reviewed literature that has reported the combined use of systems thinking approaches and implementation science constructs (within the same study), to deliver population health interventions. METHODS: A systematic literature search of peer-reviewed original research was conducted across six databases from 2009 to 2021. Journal manuscripts were included if they: (1) reported on a population health study conducted in a community, (2) reported the use of a systems method in the design of the intervention, and (3) used an implementation science theory, framework or model in the delivery of the intervention. Data extracted related to the specific systems methods and definitions and implementation science constructs used. The Mixed Methods Appraisal Tool (MMAT) was used to assess study quality. RESULTS: Of the 9086 manuscripts returned, 320 manuscripts were included for full-text review. Of these, 17 manuscripts that reported on 14 studies were included in the final extraction. The most frequently reported systems methods were a 'whole of community systems approach' (n = 4/14) and 'community-based system dynamics' (n = 2/14). Nineteen different implementation science theories, frameworks and models were used for intervention delivery, with RE-AIM being the only framework used in more than one study. CONCLUSION: There are few published peer-reviewed studies using systems thinking and implementation science for designing and delivering population health interventions. An exploration of synergies is worthwhile to operationalise alignment and improve implementation of systems thinking approaches. Review protocol registration PROSPERO CRD42021250419.

How healthy and affordable are foods and beverages sold in school canteens? A cross-sectional study comparing menus from Victorian primary schools.

OBJECTIVE: Government policy guidance in Victoria, Australia, encourages schools to provide affordable, healthy foods in canteens. This study analysed the healthiness and price of items available in canteens in Victorian primary schools and associations with school characteristics. DESIGN: Dietitians classified menu items (main, snack and beverage) using the red, amber and green traffic light system defined in the Victorian government's School Canteens and Other School Food Services Policy. This system also included a black category for confectionary and high sugar content soft drinks which should not be supplied. Descriptive statistics and regressions were used to analyse differences in the healthiness and price of main meals, snacks and beverages offered, according to school remoteness, sector (government and Catholic/independent) size, and socio-economic position. SETTING: State of Victoria, Australia. PARTICIPANTS: A convenience sample of canteen menus drawn from three previous obesity prevention studies in forty-eight primary schools between 2016 and 2019. RESULTS: On average, school canteen menus were 21 % 'green' (most healthy - everyday), 53 % 'amber' (select carefully), 25 % 'red' (occasional) and 2 % 'black' (banned) items, demonstrating low adherence with government guidelines. 'Black' items were more common in schools in regional population centres. 'Red' main meal items were cheaper than 'green'% (mean difference -$0·48 (95 % CI -0·85, -0·10)) and 'amber' -$0·91 (-1·27, -0·57)) main meal items. In about 50 % of schools, the mean price of 'red' main meal, beverages and snack items were cheaper than 'green' items, or no 'green' alternative items were offered. CONCLUSION: In this sample of Victorian canteen menus, there was no evidence of associations of healthiness and pricing by school characteristics except for regional centres having the highest proportion of 'black' (banned) items compared with all other remoteness categories examined. There was low adherence with state canteen menu guidelines. Many schools offered a high proportion of 'red' food options and 'black' (banned) options, particularly in regional centres. Unhealthier options were cheaper than healthy options. More needs to be done to bring Victorian primary school canteen menus in line with guidelines.

The implementation and effectiveness of outlet-level healthy food and beverage accreditation schemes: A systematic review.

Healthy food outlet accreditation schemes represent an avenue for incentivizing food retailers to promote healthy eating patterns by improving the healthiness of food environments. This systematic review aimed to (i) assess the impact of food outlet-level accreditation schemes on outlet practices and customer purchases and (ii) identify barriers and enablers to scheme implementation. Peer-reviewed and grey literature were systematically searched. Eligible studies related to outlet-level food and beverage accreditation schemes across any food retail setting. Findings were narratively synthesized by retailer type according to (i) scheme characteristics (governance, targeted products, support, and monitoring); (ii) scheme outcomes (rate of uptake, proportion of certified retailers, impact on purchasing, customer perspectives, and retailer perspectives); and (iii) barriers and enablers to implementation. From 21,943 records screened, 48 were included, covering 26 schemes. Most (18) targeted restaurants or convenience stores. Average uptake was 65% of all outlets approached to participate. Implementation of accreditation schemes was associated with healthier customer purchases in convenience stores, schools, and hospitals, but evidence from restaurants was mixed. Enablers of scheme implementation included support for implementation and maintenance, flexible scheme criteria, and motivated retail staff. Healthy food outlet accreditation schemes represent a promising mechanism for engaging retailers to improve the healthiness of food retail environments.

Consumer willingness to pay for healthier food products: A systematic review.

Food retail strategies to improve the healthiness of food and beverage options may increase purchasing of healthier options and improve diets. Consumer demand for healthier options is an important determinant of the successful implementation and maintenance of healthy food retail interventions. A systematic review of peer-reviewed literature was undertaken to explore whether consumers are willing to pay more for healthier foods and to determine the key factors that influence willingness to pay. Fifteen studies reported the results of 26 experiments providing willingness to pay estimates for healthier food products across a range of food retail environments. Twenty three out of the 26 experiments included in this review (88.5%) found consumers would pay a 5.6% to 91.5% (mean 30.7%) price premium for healthier foods. Studies consistently found a positive willingness to pay for foods with reduced fat and wholegrains with additional fruit and vegetables, while willingness to pay for foods with reduced salt or a combination of low fat and sugar, or salt showed mixed results. Adults over 60 years, females, those living with obesity, and consumers who aim to maintain a healthy lifestyle were more likely to pay a price premium for healthier food, whereas younger consumers, consumers with healthy weight, and consumers with higher levels of education were less likely to pay higher prices. The results of this review contribute to our understanding of consumer preferences for healthier products and provide information to retailers on consumer surplus (benefits) associated with the provision of healthier food alternatives.

Integrating nutrition and obesity prevention considerations into institutional investment decisions regarding food companies: Australian investment sector perspectives.

BACKGROUND: There is growing recognition that current food systems are both unhealthy and unsustainable, and are increasingly shifting toward the supply and marketing of unhealthy, ultra-processed foods and beverages. Large food companies hold substantial power within food systems and present a significant barrier to progress on addressing issues related to nutrition and obesity prevention. Institutional investors (such as pension funds) play a key role in influencing corporate governance and practices, and are increasingly incorporating environmental, social and governance (ESG) considerations within investment decisions. By considering nutrition and obesity prevention, institutional investors present a potential avenue for driving increased food industry accountability for their population health impact. This study investigated views of stakeholders in the Australian investment sector on the incorporation of nutrition and obesity prevention considerations within institutional investment decision-making regarding food companies. METHODS: Fifteen in-depth, semi-structured interviews were conducted in 2020-21. Participants were predominantly Australian-based, and included representatives from asset management companies, superannuation funds, ESG advisory/consultancy firms, ESG research providers, and relevant advocacy groups. Interviews examined challenges and opportunities to the integration of nutrition and obesity prevention considerations within institutional investment decision-making. Interviews were analysed using deductive thematic analysis, informed by a theoretical change model. RESULTS: Several participants reported that their institution factored nutrition and obesity prevention considerations into their investment decisions; however, attention to nutrition-related issues was limited, generally perceived as 'niche', and not yet institutionalised. Key challenges and opportunities were identified at the employee, investment organisation, investment sector, government and non-government levels. These challenges and opportunities centred around experience and knowledge, quality and availability of ESG data and benchmarks, importance of investor coalitions, and demonstration of financial risks related to nutrition and obesity. CONCLUSION: There are a range of steps that could be taken to help ensure more systematic and effective consideration of issues related to nutrition and obesity prevention within institutional investment decision-making in Australia, including: (1) improved nutrition-related reporting metrics and benchmarking criteria for food companies; (2) better articulation of the financial risks that unhealthy diets and obesity pose to investors; (3) enhanced investor advocacy on unhealthy diets and obesity through investor coalitions and; (4) detailed guidance for investors on how to address unhealthy diets and obesity. Better engagement between the Australian public health community, institutional investors and government regulators is critical to drive changed investor practice in this area.

The impact of primary school nutrition policy on the school food environment: a systematic review.

School nutrition policies that aim to address unhealthy diets have been introduced in many countries. This systematic review aimed to synthesize the international literature to determine the impact (overall and by socioeconomic position [SEP]) of primary school nutrition policies on the availability of foods and beverages in schools. Seven databases were searched using keywords and medical subject headings related to nutrition policies and schools. Studies that reported on the impact of implemented school nutrition policies on food and beverage availability within primary schools were included. Eighteen studies (reported across 20 papers) were included. Fifteen of the included studies reported some positive impacts of policies, including increased availability of healthier foods and decreased availability of less healthy foods. Five studies focused specifically on schools in low-income communities and a further three specifically compared schools by SEP, with mixed findings. Two studies reported on factors influencing policy implementation, reporting a lack of financial resources as a barrier to schools offering a wider selection of healthy foods and additional school resources as increasing the likelihood of offering healthy foods. School nutrition policies appear to be effective at improving the healthiness of foods and beverages available at schools. Furthermore, the results suggest that well-implemented school nutrition policies that improve the healthiness of foods available are unlikely to exacerbate the socioeconomic gradient of poor nutrition. However, the number of studies that reported results by SEP limits drawing strong conclusions regarding equity impacts and we strongly recommend further studies analyze their findings according to SEP.

Exploring the effects of added sugar labels on food purchasing behaviour in Australian parents: An online randomised controlled trial.

BACKGROUND: Evidence of the effects of front-of-pack added sugar labelling remains limited, especially for foods other than sugary drinks. More information is needed about which labels are likely to be most effective in reducing intended purchases of products with higher added sugar content in realistic contexts to inform policymakers' decisions. OBJECTIVE: To determine the impact of added sugar labels on intended purchases of high sugar breakfast cereals, yoghurt, and non-alcoholic beverages. METHODS: Australian parents who were regular purchasers of relevant product categories completed an online parallel randomised controlled trial from 31 August 2020 to 13 February 2021. Participants selected their intended purchase from 10 products in each of packaged beverages, breakfast cereal, and yoghurt categories after randomisation to one of seven added sugar labelling conditions in current use or under consideration by the Australian Government. Logistic regressions assessed differences between intervention and control conditions in the odds of intended purchases of a high sugar product. RESULTS: 2825 eligible participants were randomised with 2582 valid surveys analysed (Control n = 367; 'Nutrition Information Panel (NIP) with Added Sugar' n = 364; 'Teaspoons of Sugar' n = 369; 'Warning' n = 371; 'Health Star Rating (HSR) using Total Sugar' n = 368; 'HSR with Added Sugar' n = 371; 'Sugar in the Ingredients List' n = 372). No consistent effects were found on intended purchases of high sugar products overall or within product categories for any of the tested labels compared to controls (overall, 'NIP with Added Sugar': OR 1.00 [95%CI 0.83,1.20]; 'Teaspoons of Sugar': 0.94[0.80,1.11]; 'Warning': 1.10[0.93,1.30]; 'HSR with Total Sugar': 1.01[0.85,1.21]; 'HSR with Added Sugar': 1.09[0.92,1.30]; 'Sugar in the Ingredients List': 1.01[0.85,1.21]). CONCLUSIONS: Findings reinforce the importance of ensuring nutrition labelling policies are introduced as part of a suite of interventions to influence both consumer and manufacturer behaviour.

Understanding Enablers and Barriers to the Implementation of Nutrition Standards in Publicly Funded Institutions in Victoria.

Effective implementation of nutrition standards in publicly funded institutions can facilitate healthy food and beverage consumption by communities and populations, which can enable improvements in dietary intake and reduce disease burden. This study aimed to understand stakeholder perspectives on the implementation of government nutrition standards in publicly funded institutions in the Australian state of Victoria, as well as to determine enablers and barriers to successful implementation. Pre-interview questionnaires and semi-structured interviews were administered to stakeholders involved in the implementation of nutrition standards in publicly funded institutions in Victoria. The Interactive Systems Framework, which allows understanding of the infrastructure and systems needed to implement policies, was used to design the survey instruments and guide the data analysis. Forty-four stakeholders were interviewed, including program implementers, support personnel and food providers, across public sector hospitals and health services, workplaces, sport and recreation centres and schools. Though translated materials and resources have been developed for end-users to facilitate uptake and implementation, current nutrition standards were perceived to be long and complex, which hindered implementation. The existence of a government-funded implementation support service enabled action by providing technical support, troubleshooting and capacity-building. A specific pathway for successful guideline implementation was determined through the analysis. Opportunities to close the policy-implementation gap were identified. This will be crucial to maximising the impact of nutrition standards on population diets and reducing diet-related disease. Strengthening the guidelines and their governance, streamlining the support system and overcoming barriers within and outside of implementing organisations, are urgently required to propel statewide progress.

Local government policies on healthy food promotion and obesity prevention: results from a national Australian survey.

OBJECTIVE: Local governments (LGs) often own or manage sport and recreation facilities and can promote health in these settings by implementing healthy food policies. The primary aim of this study was to assess the policies, attitudes and practices of Australian LGs relating to obesity prevention and the provision of healthy food in this setting. METHODS: In July 2020, all 539 Australian LGs were invited to complete a survey. We assessed LG priorities to obesity prevention, promoting healthy eating and public health as well as the presence of healthy food policies in sporting facilities. RESULTS: 203 (38%) LGs completed the survey. Improving public health was a high priority, while obesity prevention and promoting healthy eating were a medium priority. 22% of LGs reported that the priority given to promoting healthy food had increased over the previous year and stayed the same at 65%. Ten per cent of LGs had a healthy food and drink policy in sporting facilities, with 32% reporting having made changes without a policy. LGs located in major cities, with larger populations and with more facilities reported having made more healthy changes at their facilities. CONCLUSION: Promoting health is a priority for LGs across Australia, but very few have policies relating to the food environments in their sporting facilities. IMPLICATIONS FOR PUBLIC HEALTH: Ongoing monitoring is important to assess changes over time and identify LGs where greater support is required.

Change in the Healthiness of Foods Sold in an Australian Supermarket Chain Following Implementation of a Shelf Tag Intervention Based on the Health Star Rating System.

INTRODUCTION: Most people in Australia buy most of their food in supermarkets. Marketing techniques promoting healthy foods in supermarkets can be important to encourage healthy eating at a population level. Shelf tags that highlight the healthiness of products have been identified as one such promising initiative. The aim of this study was to assess changes in the healthiness of foods sold in an Australian supermarket chain following implementation of a shelf tag intervention based on the Australian Health Star Rating (HSR) system. METHODS: A controlled, non-randomised trial was undertaken in seven supermarkets (intervention: n = 3; control: n = 4) of a single chain in Victoria, Australia, over 12 weeks (4 weeks baseline, 8 weeks intervention period) between August and November 2015. The intervention involved provision of a shelf tag indicating the HSR of all packaged products that scored 4.5 or 5 stars ('high-HSR products') using the Australian HSR system. Posters indicating the healthiness of fresh fruits and vegetables (not eligible for an HSR rating, as they are not packaged) were also installed. Weekly per store sales data were provided by the retailer. In an intention-to-treat analysis (with intervention status of individual products based on their eligibility to be tagged), the proportion (%) of all 'high-HSR' packaged food sold and the volume of key nutrients (saturated fat, total fat, sodium, total sugar, protein, carbohydrates and energy) per 100 g sold were assessed. Difference-in-difference analyses were conducted to determine the difference between intervention and control stores in terms of mean outcomes between baseline and intervention periods. Customer exit surveys (n = 304) were conducted to evaluate awareness and use of the shelf tags and posters. RESULTS: The proportion of 'high-HSR products' sold increased in the intervention period compared to the baseline period in each of the three intervention stores (average increase of 0.49%, 95% CI: -0.02, 0.99), compared to a decrease of -0.15% (-0.46, 0.15) in control stores (p = 0.034). The overall increase in intervention compared to control stores (difference-in-difference) of 0.64% represents an 8.2% increase in the sales of 'high-HSR products'. Sales of total sugar, total fat, saturated fat, carbohydrates, sodium, protein and total energy in packaged food all decreased significantly more in intervention stores compared to control stores. Sales of fresh fruits and vegetables decreased in intervention stores compared to control stores. Customer surveys found that 34.4% noticed the shelf tags. Of those who noticed the tags, 58% believed the shelf tags influenced their purchases. CONCLUSIONS: With this study, we found that the use of shelf tags that highlight the healthiest packaged foods in a supermarket setting showed promise as a mechanism to improve the healthiness of purchases. Opportunities to scale up the intervention warrant exploration, with further research needed to assess the potential impact of the intervention on overall population diets over the longer term.

Cost-Benefit and Cost-Utility Analyses to Demonstrate the Potential Value-for-Money of Supermarket Shelf Tags Promoting Healthier Packaged Products in Australia.

The supermarket environment impacts the healthiness of food purchased and consumed. Shelf tags that alert customers to healthier packaged products can improve the healthiness of overall purchases. This study assessed the potential value-for-money of implementing a three-year shelf tag intervention across all major supermarket chains in Australia. Cost-benefit analyses (CBA) and cost-utility analyses (CUA) were conducted based on results of a 12-week non-randomised controlled trial of a shelf tag intervention in seven Australian supermarkets. The change in energy density of all packaged foods purchased during the trial was used to estimate population-level changes in mean daily energy intake. A multi-state, multiple-cohort Markov model estimated the subsequent obesity-related health and healthcare cost outcomes over the lifetime of the 2019 Australian population. The CBA and CUA took societal and healthcare sector perspectives, respectively. The intervention was estimated to produce a mean reduction in population body weight of 1.09 kg. The net present value of the intervention was approximately AUD 17 billion (B). Over 98% of the intervention costs were borne by supermarkets. CUA findings were consistent with the CBA-the intervention was dominant, producing both health benefits and cost-savings. Shelf tags are likely to offer excellent value-for-money from societal and healthcare sector perspectives.

Factors Influencing Implementation, Sustainability and Scalability of Healthy Food Retail Interventions: A Systematic Review of Reviews.

The aim of this systematic review of reviews was to synthesise the evidence on factors influencing the implementation, sustainability and scalability of food retail interventions to improve the healthiness of food purchased by consumers. A search strategy to identify reviews published up until June 2020 was applied to four databases. The Risk of Bias in Systematic Review tool was used. Review findings were synthesised narratively using the socio-ecological model. A total of 25 reviews met the inclusion criteria. A number of factors influenced implementation; these included retailers' and consumers' knowledge and preferences regarding healthy food; establishing trust and relationships; perceived consumer demand for healthy food; profitability; store infrastructure; organizational support, including resources; and enabling policies that promote health. Few reviews reported on factors influencing sustainability or scalability of the interventions. While there is a large and rapidly growing body of evidence on factors influencing implementation of interventions, more work is needed to identify factors associated with their sustainability and scalability. These findings can be used to develop implementation strategies that consider the multiple levels of influence (individual, intrapersonal and environmental) to better support implementation of healthy food retail interventions.

Implementation and sales impact of a capacity building intervention in Australian sporting facility food outlets: a longitudinal observational study.

Background: Few studies have explored behavioural and financial impacts of retail initiatives after 2 years to address the unhealthy food environments common in local government sporting settings. Aims: To evaluate the impact of a 2-year local government capacity building intervention in sporting facility food outlets on (1) the healthiness of refrigerated drink choices available and visible to customers, (2) healthiness of refrigerated drinks sold and (3) refrigerated drink revenue. Methods: 52 sporting facilities within 8 local governments from Victoria, Australia, participated in an intervention between March 2018 and February 2020 by limiting 'red' (least healthy) drinks to ≤20% of refrigerator display and increasing 'green' (healthiest) drinks to ≥50% of display. Mixed models assessed changes in mean percentage of 'red', 'amber' and 'green' drinks displayed over time, compared with baseline.Facilities provided electronic weekly itemised sales data (December 2015 to February 2020). Weekly volume of 'red' or 'green' drinks sold as a proportion of total drinks sold, and total refrigerated drinks revenue were compared preimplementation and postimplementation using mixed models (seasonal facilities), and mixed-effect interrupted time series models (non-seasonal facilities). Results: Display of 'red' drinks decreased by mean -17.1 percentage points (pp) (95% CI -23.9 to -10.3) and 'green' drinks increased 16.1 pp (95% CI 9.30, 22.9) between baseline and 18-month audits.At nine seasonal facilities, compared with the summer preimplementation, the mean volume of 'red' drinks sold decreased by -19.0 pp (95% CI -28.6, to -9.51) and refrigerated drink revenue decreased by-AU$81.8 (95% CI -AU$123 to -AU$40.8) per week. At 15 non-seasonal facilities, by February 2020, the volume of 'red' drinks sold decreased on average by -11.0 pp (95% CI -21.6 to -0.41) with no change in drink revenue. Conclusion: Reducing the display of unhealthy drinks can be an effective public health policy to improve the healthiness of customer purchases, provided there is consideration of potential impacts on revenue.

A Proposed Research Agenda for Promoting Healthy Retail Food Environments in the East Asia-Pacific Region.

PURPOSE OF REVIEW: This paper aimed to summarise existing literature on strategies to improve the healthiness of retail food environments in the East Asia and Pacific (EAP) region, and propose a prioritised research agenda on this topic. RECENT FINDINGS: Little research on retail food environments has been conducted in the EAP region. Several approaches for measuring retail food environments were identified, although none have been tailored to the EAP context. A small number of policies and initiatives to promote healthy retail food environments have been implemented in EAP. Lessons learnt from successful implementation of initiatives in other regions could be applied in EAP. Retail food environments have a strong influence on food choices and health outcomes. Research can contribute to efforts to improve the healthiness of retail food environments in EAP by (1) describing the current state of retail food environments to highlight areas of good practice and concern and (2) identifying policies and initiatives that are likely to be effective, and mechanisms for their successful implementation.

Favorable Commercial and Health Behavior Impacts of a Healthy Vending Policy at an Australian University.

BACKGROUND: The World Health Organization recognizes universities as an important health-promotion setting, including in healthy food provision. Previous research shows that healthy food retail interventions also need to consider commercial sustainability, including financial outcomes, and should take a holistic approach to consumer experience. OBJECTIVE: Our aim was to determine the health behavior and commercial outcomes of a multicomponent traffic light-based healthy vending policy implemented as one part of a holistic university food policy. The hypothesis was that purchases of less healthy "red" beverages would decrease compared with predicted sales, that purchases of healthier "green" and "amber" alternatives would increase, and that there would be no change in revenue. DESIGN: A quasi-experimental design evaluated a real-world food policy using monthly aggregated sales data to compare pre-intervention (January 2016 to March 2018) and post-intervention period sales (December 2018 to December 2019). PARTICIPANTS/SETTING: Electronic sales data were collected from 51 beverage vending machines across 4 university campuses in Victoria, Australia. INTERVENTION: A multicomponent policy was implemented between April and November 2018. Beverages were classified using a voluntary state government traffic light framework. Policy included display ≤20% red beverages and ≥50% green beverages; machine traffic light labeling; health-promoting machine branding; review of machine placement; and recycled bottle packaging. MAIN OUTCOME MEASURES: Changes in red, amber, and green volume sales, and revenue compared with predicated sales. STATISTICAL ANALYSES PERFORMED: Interrupted time series analysis of sales data compared post-policy sales with predicted sales. RESULTS: In the 13th month post-policy implementation, there was a 93.2% (95% CI +35.9% to +150.5%) increase in total beverage volume sold and an 88.6% (95% CI +39.2% to +138.1%) increase in revenue. There was no change in red beverage volume sold, but increases in green (+120.8%; 95% CI +59.0% to +182.6%) and amber (+223.2%; 95% CI +122.4% to +323.9%) volume sold. CONCLUSIONS: Sustained behavior change and commercial outcomes suggest that holistic vending interventions can effectively promote healthier beverage sales.
